DS12 has been at a friends for dinner tonight and just phoned to say he's been invited to stay. I said that was fine, did he need anything dropped off. He then said it would be him and the friend home alone until 11pm. At this point I said he couldn't stay.
I think I'm quite influenced by how strict my own upbringing was, so I don't know if AIBU. He does plenty of sleepovers, but never with this friend and I feel a bit rotten.
